Water solubility
Administrative data
Link to relevant study record(s)
- Endpoint:
- water solubility
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 18 May 2010 – 04 June 2010
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: This study has been performed according to OECD and EC guidelines and according to GLP principles.
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 105 (Water Solubility)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.6 (Water Solubility)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- flask method
- Water solubility:
- > 1 000 g/L
- Temp.:
- 20 °C
- Remarks on result:
- other: The pH of water mixture could not be determined due to the high viscosity of the sample.
- Details on results:
- After the stirring period, the test sample was clear and no undissolved test substance was observed. From this, it was concluded that the water solubility of Alkylamidoamine glycinate, majority in C12 & 14 (amphoacetate) – Dried Sample at 20°C was > 1 x 10^3 g solids/L.
- Conclusions:
- The water solubility of the substance is > 1 kg/L
Reference
Description of key information
The water solubility of the substance was found to exceed 1000 mg/L. The critical micelle concentrations of the two representative substances were determined to be 160 and 157.51 mg solids/L.
Key value for chemical safety assessment
- Water solubility:
- 1 000 g/L
- at the temperature of:
- 20 °C
Additional information
The water solubility of the substance has been determined by visual observation in accordance with OECD 105 (1995), EU Method A.6 (2008), EPA OPPTS 830.7840 (1998) and according to
GLP principles. In addition, the critical micelle concentration was determined for two substances representative for the registered substances by measuring the surface tension of solutions at eight different substance concentrations according to a method based on ISO 4311. The critical micelle concentrations of the two substances were determined to be 160 and 157.51 mg solids/L.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
